Why people look up 180 days ago
One hundred and eighty days ago is about six months: the window to file a discrimination charge with the EEOC in most cases, and a common look-back for travel and residency rules.
Some visa rules count days in a rolling 180-day window, such as the Schengen 90/180 rule for short stays in Europe.

How 180 days ago is counted
The calculator takes today's date on your device and subtracts 180 calendar days, so it is right in your own time zone and accounts for months of different lengths and leap years. 180 days is 25 weeks and 5 days, or about 5.9 months. Calendar days include weekends and public holidays. If a rule talks about business days instead, use the business days calculator and count backwards.
Legal and financial deadlines often count from a specific event, such as the date a statement was sent or a notice was received, rather than from today. Enter that date as the start date above and choose Subtract to count back, or Add to find a deadline.
